Causes of chronic pelvic pain

Symptomatology and knowledge regarding pelvic floor dysfunctions and influence of gender stereotypes in female athletes

Pelvic floor dysfunctions (PFD) are highly prevalent among females who do athletics, a sport requiring jumping, strength, and running. Although educational approaches are useful options, the educational need for this particular population remains unknown. The objective of the present study was to describe the level of knowledge regarding PFD and its relationship with symptomatology and gender stereotypes in female athletes in Spain. A total of 255 female athletes completed an anonymous online survey to explore their knowledge regarding urinary incontinence (UI), pelvic organ prolapse (POP), anal incontinence (AI), and sexual dysfunction (SexD), as well as their PFD symptoms and gender stereotyped beliefs related to sport. Educational level and sports characteristics (training volume, experience, and athletic modality) were also explored. Participants demonstrated a low level of knowledge in terms of POP (52.5%), AI (64.0%), and SexD (40%), but not for UI (70.8%). The proportion of PFD complaints was 63.5% for dyspareunia, 51.8% for urine leakage, 42.4% for pelvic pain, 17.3% for AI, and 9.0% for POP, with no associations with knowledge (p > 0.05). Lower knowledge about UI and SexD was related to greater gender stereotypes (p < 0.05) and rejection of professional healthcare (p = 0.010). As a conclusion, the level of knowledge about PFD was low in female athletes who train and compete in athletics in Spain, mainly with regard to sexual dysfunction. Although 63.5% of athletes had dyspareunia and 51.8% urinary leakages, symptomatology was not associated with level of knowledge. However, a lower level of knowledge was associated with more stereotyped beliefs and rejection of professional healthcare for PFD. These findings confirm the need to design appropriate educational interventions to disseminate information on all the types of PFD, particularly sexual contents. The potential influence of gender stereotypes makes it appropriate to include the gender perspective in these interventions.

Using Myofascial Therapy to Improve Psychological Outcomes, Quality of Life, and Sexual Function in Women with Chronic Pelvic Pain-A Case Series

(1) Background: Chronic pelvic pain represents a prevalent condition afflicting women. Research has highlighted the presence of psychological distress and sexual dysfunction in these individuals. Regrettably, myofascial pelvic pain often goes unnoticed and untreated despite its integral role in chronic pelvic pain. (2) Methods: By employing a longitudinal case series design, we studied eighteen women afflicted with chronic pelvic pain. Over a 12-week period, these participants underwent 15 sessions of myofascial therapy. Data encompassing sociodemographic particulars, the Hospital Anxiety and Depression Scale, the Medical Outcomes Study Short Form 12 questionnaire, and the Female Sexual Function Index were collected at baseline, 12 weeks post-intervention, and again at the 24-week mark. (3) Results: After a span of 12 weeks subsequent to the intervention, the participants demonstrated noteworthy enhancements (p < 0.001) in their depression and anxiety scores, their overall Mental Component scores in the Medical Outcomes Study Short Form 12, as well as sexual function. Importantly, these gains were sustained at the 24-week juncture post-therapy. (4) Conclusions: The findings stemming from our prospective case study underscore the potential utility of myofascial therapy for women grappling with chronic pelvic pain. This form of intervention yields significant advancements in alleviating anxiety, depression, health-related quality of life, and sexual function.

Preoperative quality of life at time of gynecologic surgery: considerations for postoperative management

BACKGROUND

Patients presenting for gynecologic surgery are a heterogeneous group. Preoperative quality of life may be a useful tool to guide postoperative management.

OBJECTIVE

This study aimed to examine the key drivers of preoperative quality of life to improve counseling and postoperative management.

STUDY DESIGN

This study analyzed preoperative survey results from 154 participants using the following surveys: National Institutes of Health Toolbox Global Health v1.2, Gastrointestinal: Gas and Bloating v1.1 13a, Gastrointestinal: Diarrhea v1.0 6a, and Sexual Function and Satisfaction Brief Profile (Female) v2.0, Perceived Stress Scale, the Vaginal Assessment Scale, and the Vulvar Assessment Scale. Survey results in the form of T-scores were compared in patients with endometrial cancer and patients with benign gynecologic conditions using the Kruskal-Wallis test. The multivariate analysis was performed using linear regression to adjust the comparisons for age, body mass index, and comorbidity.

RESULTS

Of the 154 patients, preoperative diagnosis was benign in 66% (n=102) and endometrial cancer in 34% (n=52). Patients with endometrial cancer were more likely to be older, non-White, in lower income brackets, have higher body mass index, and be postmenopausal (P<.05). Although preoperative global health scores were similar between benign and malignant cases (P>.05), when adjusted for age, the differences in global health quality of life between patients with benign gynecologic conditions and those with endometrial cancer became significant, because the endometrial cancer group was older than the benign group (P<.05). However, when adjusting for age, body mass index, and comorbidities (hypertension and diabetes), the differences were no longer significant (P>.05). Sexual interest was decreased in the patients with endometrial cancer both in the unadjusted and adjusted model; and vulvar complaints became significantly different between the groups when controlling for body mass index, age, and comorbidities (P<.05).

CONCLUSION

Despite substantial differences in preoperative diagnosis, preoperative quality of life is highly influenced by age, body mass index, and comorbidities. Therefore, these factors should be explored in surgical outcomes and postoperative management trials.

Management of Patients when Superficial Venous Disease Arises from Pelvic Escape Points

Chronic pelvic pain (CPP) is a common condition in women that carries with it significant morbidity. It is commonly seen in patients presenting to obstetrics and gynecology outpatient clinic visits. CPP is a presenting symptom of various pathologies including pelvic varicocele, pelvic adhesions, spastic colon syndrome, uterine fibroids, endometriosis, and psychosomatic disorders. Pelvic congestion syndrome has more recently been termed "pelvic venous insufficiency (PVI)" due to the underlying retrograde flow through incompetent ovarian and pelvic veins that are thought to cause the symptoms of CPP. Pelvic varices can commonly present alongside vulvar, perineal, and lower extremity varices. There are some predictable "escape pathways" for these varices that may present for interventional treatment. This article introduces the reader to current terminology, clinical presentation, diagnosis, and treatment of patients with pelvic varices due to PVI.

Sexual Satisfaction and Frequency of Orgasm in Women With Chronic Pelvic Pain due to Endometriosis

BACKGROUND

Dyspareunia, one of the main symptoms of the chronic gynecological pelvic pain disorder endometriosis, may interfere with the likelihood of reaching an orgasm, yet for women with dyspareunia, no data on orgasm rates in different sexual activities are available.

AIM

The aim of this study was to evaluate the ability to reach an orgasm and its association with sexual satisfaction during different sexual activities in women with a chronic pelvic pain disorder and in healthy control women.

METHODS

A set of questionnaires including the brief index of sexual functioning and global sexual functioning was used to evaluate sexuality in women affected with endometriosis (n = 434) and a nonaffected control group (n = 434) recruited in German-speaking countries.

OUTCOMES

The primary outcome measure of this study was the orgasm rate during different types of sexual activities.

RESULTS

Only the ability to have an orgasm during sexual intercourse (P = .002) but not during masturbation (P = .509) or partnered noncoital sexual activities (P = .229) is affected by endometriosis. Dyspareunia was associated with a reduced ability to experience an orgasm during intercourse for endometriosis patients (P = .020) and control women (P = .006). The ability to orgasm during noncoital sexual activities (P = .006) and sexual intercourse (P = .038) was associated with a higher sexual satisfaction in women with endometriosis. For controls, only the ability to achieve an orgasm with sexual intercourse was associated with sexual satisfaction (P = .038).

CLINICAL IMPLICATIONS

Sexual counselling as part of medical support could help couples living with chronic pelvic pain of the female partner integrate noncoital sexual activities in their sex lives, leading to fewer sex-related problems and higher sexual desire and satisfaction.

STRENGTHS AND LIMITATIONS

This study is the first to examine different ways of achieving an orgasm and sexual satisfaction in a large group of women with endometriosis and a matched control group. The breadth of the questionnaire allowed a differentiated analysis of factors influencing the likelihood of achieving an orgasm and overall sexual satisfaction. The one limitation is that the length and the intimate nature of the questionnaire possibly resulted in reluctance to answer this part of the questionnaire.

CONCLUSION

Partnered noncoital sexual activities may represent an alternative to reach orgasm for women with endometriosis-related chronic pelvic pain or anorgasmia during sexual intercourse.

Sigmoid cancer mimicking ovarian echotexture on transvaginal ultrasound: Case report with literature review

Ultrasound is a first line imaging modality for the evaluation of female pelvic pain. Pelvic pain constitutes one of the most common reasons for presentation to the emergency department with increasing use of point of care ultrasound. Infrequently, point of care or formal ultrasound evaluation may lead to misdiagnosis of extraovarian disease. This can have serious consequences, especially if an extraovarian malignancy is mistaken for a normal ovary or an ovary with a benign process. We present a case of a 41-year-old female who presented to the emergency department for a chief complaint of pelvic pain and vaginal bleeding. Transvaginal ultrasound demonstrated a left adnexal mass, later characterized as a sigmoid colon cancer on MRI and pathology, simulating ovarian echotexture with peripheral hypoechoic components resembling follicles. This article will review the literature of various cases of extraovarian pathology misidentified as ovarian processes and highlight the importance of considering these extraovarian mimickers to prevent potential morbidity and mortality of a missed diagnosis.

Do static and dynamic activities induce potentially damaging breast skin strain?

Background/Aim

This study aimed to quantify breast skin strain and strain rate and the effect of support garments at reducing strain and to determine characteristics that correlate with strain during static and dynamic activity.

Methods

39 women (UK size 32C to 36G) had electromagnetic sensors applied to their breast skin. Sensor coordinates were recorded while standing, walking, running, in no, low and high breast support conditions, plus bare-breasted in the estimated neutral position to calculate strain. Relative breast coordinates and 35 inter-sensor distances identified peak breast skin strain (%) and strain rate (%·s^-1), which were then correlated with nipple kinematics, breast pain and participant characteristics.

Results

Mean peak breast skin strain was generally <60% during standing, walking and running; however, some individuals exhibited 93% strain in bare-breasted running. Compared with low support, high support did not further reduce strain during standing and walking. Peak breast skin strain/strain rate location was longitudinal, in lateral and medial breast regions and displayed strong correlations with breast volume, body mass index and bust circumference.

Conclusion

Static and dynamic activity did not result in excessive breast skin strain, suggesting low risk of skin damage. However, during running, some individuals experienced excessive skin strains (up to 93%) and strain rates (up to 1258%·s^-1). Breast skin strain/strain rate location suggests lift is required in the lateral and medial bra cup to reduce strain, particularly in larger breast volumes due to increased skin strain risk.

[Effectiveness of multimodal rehabilitation (biofeedback plus capacitive-resistive radiofrequency) on chronic pelvic pain and dyspareunia: prospective study and literature review]

OBJECTIVE

To determine whether a multimodal rehabilitation protocol (Biofeedback [BFB] plus capacitive-resistive [INDIBA®] radiofrequency [RF]) reduces pain and increases muscular strength in patients with chronic pelvic pain (CPP) and dyspareunia.

MATERIAL AND METHODS

We performed a prospective, quasi-experimental, before-after study in 37 patients with CPP and/or dyspareunia referred to the Rehabilitation Department of Hospital Universitario Santa Cristina (January 2016 to December 2018). The protocol consisted of 8 sessions of pelvic floor exercises assisted by manometric BFB (15min of tonic/phasic exercises each) supervised by a physiotherapist, followed by suprapubic and perineovaginal bipolar RF [capacitive(5 min)/resistive(10 min)]. The variables evaluated were pain (VAS 0-10) and strength (mmHg) of the pelvic floor musculature and the start/end of the treatment.

RESULTS

The mean age was 41.5±12.65 years. The prevalence was higher among women aged 21-40 years (n=20, 54%) and those aged 41-60 years (n=12; 32.4%). Dyspareunia was present in 34 patients (91.8%), and non-specific CPP in 3 (8.2%). The protocol improved pain (from 7.27±1.34 to 3.75±2.21 points), maximal muscular strength (from 25.56±15.9mmHg to 35.35±20.4mmHg) and mean muscular strength (from 4.86±3.53mmHg to 7.18±4.46mmHg) respectively (p<0.0001).

CONCLUSION

CPP and dyspareunia are a diagnostic challenge that requires multidisciplinary management. Treatment should be started early and should consist of distinct therapeutic modalities. The protocol of multimodal rehabilitation including BFB and capacitive-resistive RF reduces pain and improves strength in patients with CPP and dyspareunia.

Outcomes of sacral neuromodulation for chronic pelvic pain: a Finnish national multicenter study

BACKGROUND

The aim of this study was to report the outcomes of sacral neuromodulation (SNM) in chronic pelvic pain (CPP) patients in the Finnish national cohort.

METHODS

This was a register-based retrospective study, involving all the centers that provide SNM treatment in Finland. The data of all patients treated with SNM for CPP were gathered from Oulu-, Turku-, Tampere- and Helsinki University Hospitals, as well as Jyväskylä and Seinäjoki Central Hospitals. All patients who had been tested for SNM implantation prior to April 2017 were included in the study.

RESULTS

A total of 51 patients were selected for SNM treatment due to CPP from 2004 until 2017. The mean follow-up time was 13.8 months (SD 22.9 months). A total of 28 patients (57%) advanced from testing to permanent stimulator implantation. There were 21 patients (41%) who had a working modulator implanted at the end of follow-up. Patients with endometriosis-related pain had a significantly higher permanent implantation rate than the overall implantation rate (88% vs. 57%; p = 0.01). The endometriosis patients also had a higher overall success rate by the end of the follow-up (75% vs. 41%; p = 0.026) CONCLUSIONS: SNM may be a viable treatment option for patients with CPP due to endometriosis. Further research on SNM treatment for endometriosis patients with refractory CPP is needed.

Potential Mechanisms Underlying Centralized Pain and Emerging Therapeutic Interventions

Centralized pain syndromes are associated with changes within the central nervous system that amplify peripheral input and/or generate the perception of pain in the absence of a noxious stimulus. Examples of idiopathic functional disorders that are often categorized as centralized pain syndromes include fibromyalgia, chronic pelvic pain syndromes, migraine, and temporomandibular disorder. Patients often suffer from widespread pain, associated with more than one specific syndrome, and report fatigue, mood and sleep disturbances, and poor quality of life. The high degree of symptom comorbidity and a lack of definitive underlying etiology make these syndromes notoriously difficult to treat. The main purpose of this review article is to discuss potential mechanisms of centrally-driven pain amplification and how they may contribute to increased comorbidity, poorer pain outcomes, and decreased quality of life in patients diagnosed with centralized pain syndromes, as well as discuss emerging non-pharmacological therapies that improve symptomology associated with these syndromes. Abnormal regulation and output of the hypothalamic-pituitary-adrenal (HPA) axis is commonly associated with centralized pain disorders. The HPA axis is the primary stress response system and its activation results in downstream production of cortisol and a dampening of the immune response. Patients with centralized pain syndromes often present with hyper- or hypocortisolism and evidence of altered downstream signaling from the HPA axis including increased Mast cell (MC) infiltration and activation, which can lead to sensitization of nearby nociceptive afferents. Increased peripheral input via nociceptor activation can lead to “hyperalgesic priming” and/or “wind-up” and eventually to central sensitization through long term potentiation in the central nervous system. Other evidence of central modifications has been observed through brain imaging studies of functional connectivity and magnetic resonance spectroscopy and are shown to contribute to the widespreadness of pain and poor mood in patients with fibromyalgia and chronic urological pain. Non-pharmacological therapeutics, including exercise and cognitive behavioral therapy (CBT), have shown great promise in treating symptoms of centralized pain.

Iatrogenic Pelvic Pain: Surgical and Mesh Complications

Female stress urinary incontinence and pelvic organ prolapse are prevalent conditions in adult women. Among treatment alternatives, more traditional methods of surgical intervention have been supplanted by synthetic polypropylene mesh kits. However, novel complications with mesh-related exposure, pelvic pain alone or with dyspareunia, and increased incidence of revision surgeries, resulted in 2 FDA warnings on transvaginal mesh use for prolapse repair. This review examines the anatomy of the vagina and urethra, the etiology of pain related to mesh use, and the relevant surgical techniques for management of this complication along with their outcomes.

Multifactorial contributors to the severity of chronic pelvic pain in women

BACKGROUND

Chronic pelvic pain affects ∼15% of women, and is associated with significant societal cost and impact on women's health. Identifying factors involved in chronic pelvic pain is challenging due to its multifactorial nature and confounding between potential factors. For example, while some women with endometriosis have chronic pelvic pain, there may be comorbid conditions that are implicated in the chronic pelvic pain rather than the endometriosis itself.

OBJECTIVE

We sought to explore multifactorial variables independently associated with the severity of chronic pelvic pain in women.

STUDY DESIGN

We used baseline cross-sectional data from an ongoing prospective cohort, collected from patient online questionnaires, physical examination, and physician review of medical records. Participants were recruited from a tertiary referral center for endometriosis and chronic pelvic pain in Vancouver, British Columbia, Canada, from December 2013 through April 2015. Exclusion criteria included menopausal status or age >50 years. Primary outcome was self-reported severity of chronic pelvic pain in the last 3 months (0-10 numeric rating scale). Potential associated factors ranged from known pain conditions assessed by standard diagnostic criteria, validated psychological questionnaires, musculoskeletal physical exam findings, as well as pain-related, reproductive, medical/surgical, familial, demographic, and behavioral characteristics. Mann-Whitney, Kruskal-Wallis, or Spearman test were used to identify variables with an association with the primary outcome (P < .05), followed by multivariable linear regression to control for confounding and to identify independent associations with the primary outcome (P < .05).

RESULTS

Overall, 656 women were included (87% consent rate), of whom 55% were diagnosed with endometriosis. The following factors were independently associated with higher severity of chronic pelvic pain: abdominal wall pain (P = .005), pelvic floor tenderness (P = .004), painful bladder syndrome (P = .019), higher score on Pain Catastrophizing Scale (P < .001), adult sexual assault (P = .043), higher body mass index (P = .023), current smoking (P = .049), and family history of chronic pain (P = .038). Severity of chronic pelvic pain was similar between women with and without endometriosis.

CONCLUSION

Multifactorial variables independently associated with severity of chronic pelvic pain were identified, ranging from myofascial/musculoskeletal, urological, family history, and psycho-social factors. Continued research is required to validate these factors and to determine whether any are potentially modifiable for the management of chronic pelvic pain.

Evaluation of the sacral nerve plexus in pelvic endometriosis by three-dimensional MR neurography

PURPOSE

To investigate the feasibility of three-dimensional MR neurography (3D MRN) for the sacral plexus using sampling perfection with application-optimized contrasts using different flip angle evolution (SPACE) sequences, and to demonstrate structural abnormalities in the pelvic nerve of women with pelvic endometriosis.

MATERIALS AND METHODS

Twenty patients with pelvic endometriosis and 20 healthy controls were examined by contrast-enhanced 3D short time inversion recovery T2-weighted imaging (CE 3D STIR T2WI) SPACE sequences on 3 Tesla MRI. Image quality and diagnostic confidence of the sequences in identifying abnormalities of the sacral plexus were analyzed and compared with conventional three-plane images of 2D turbo-spin echo T2-weighted images (2D TSE T2WI). The changes in the sacral plexus caused by endometrial lesions were evaluated.

RESULTS

The sacral plexus was clearly revealed in both healthy controls and patients with endometriosis on 3D STIR SPACE images. A good agreement was reached in the evaluation of both imaging quality (Kappa value [κ] = 0.73-1.00) and diagnostic confidence (κ = 0.66-0.81) when compared between the two independent readers. Abnormalities caused by endometriosis were identified in 17 patients, unilaterally in 10 patients, and bilaterally in 7 patients. Nerve fiber abnormalities of lumbar 5 (L5) were detected in 11 patients, of sacral 1 (S1) in 14 patients and of sacral 2 (S2) in 9 patients.

CONCLUSION

CE 3D STIR SPACE sequences demonstrate its significant capacity to investigate and map the sacral plexus, and reveal the compression and adhesion of the sacral plexus nerve as a result of ectopic lesions.

Chronic pelvic pain in women: an epidemiological perspective

Chronic pelvic pain (CPP) is common in women of reproductive age and has a significant impact on quality of life, work efficiency and healthcare utilization. CPP can be a manifestation of many different, often multifactorial conditions, and in the absence of an identified cause, the management can be particularly challenging. High quality epidemiological studies would improve the understanding of CPP and identify risk factors which may be targeted for the development of appropriate management strategies. This review focuses on what is known about the prevalence, risk factors, individual and societal burden of CPP and outlines important management strategies.

Prevalence and risk factors of pelvic pain

OBJECTIVES

To determine the prevalence of Chronic Pelvic Pain (CPP) symptoms in Malaga and its province and to identify risk factors associated.

METHOD

a cross-sectional study was carried out in Malaga and its province, 18-65 years-old throughout a non-probability sampling by quotas (n = 887), stratified by sex, age and counties. All participants completed the QCPP-M, a self-administered questionnaire, validated tool due to its ability to discriminate patients with and without CPP.

RESULTS

prevalence of symptoms of CPP in subjects between 18-65 years-old was 22.8% in general population (30.9% women and 15.6% men) (RR = 1.974 for women versus men, 95% CI 1.53-2.55, P < .001). After correction by sex and age individuals who practice physical activity had a lower score in QCPP-M that others who do not not (mean difference -0.65 ± 0.27). They were significantly associated with higher scores in the following factors: lifting and/or moving weights in activities of daily life (1.34 ± 0.33), laxatives intake and/or high-fiber diet (2.09 ± 0.48), having suffered from urogenital infectious disease in the past: vulvovaginitis, cystitis and prostatitis (1.77 ± 0.55), hemorrhoids/anal fissure (1.31 ± 0.40) or pelvic trauma (1.21 ± 0, 61) respectively. Individuals who spend more time standing had a tendency to have higher scores on QCPP-M (coefficient of regression adjusted for sex and age of 0.078 points/hour, SE = 0.04, P < .068).

CONCLUSIONS

High prevalence of CPP symptoms in Málaga (22.8%), this is related with significantly several risk factors.

Vaginal hypersensitivity and hypothalamic-pituitary-adrenal axis dysfunction as a result of neonatal maternal separation in female mice

Early life stress can permanently alter functioning of the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the stress response and influences the perception of pain. Chronic pelvic pain patients commonly report having experienced childhood neglect or abuse, which increases the likelihood of presenting with comorbid chronic pain and/or mood disorders. Animal models of neonatal stress commonly display enhanced anxiety-like behaviors, colorectal hypersensitivity, and disruption of proper neuro-immune interactions in adulthood. Here, we tested the hypothesis that early life stress impacts vaginal sensitivity by exposing mice to neonatal maternal separation (NMS) for 3h/day during the first two (NMS14) or three (NMS21) postnatal weeks. As adults, female mice underwent vaginal balloon distension (VBD), which was also considered an acute stress. Before or after VBD, mice were assessed for anxiety-like behavior, hindpaw sensitivity, and changes in gene and protein expression related to HPA axis function and regulation. NMS21 mice displayed significantly increased vaginal sensitivity compared to naïve mice, as well as significantly reduced anxiety-like behavior at baseline, which was heightened following VBD. NMS21 mice exhibited significant thermal and mechanical hindpaw hypersensitivity at baseline and following VBD. NMS14 mice displayed no change in anxiety-like behavior and only exhibited significantly increased hindpaw mechanical and thermal sensitivity following VBD. Centrally, a significant decrease in negative regulation of the HPA axis was observed in the hypothalamus and hippocampus of NMS21 mice. Peripherally, NMS and VBD affected the expression of inflammatory mediators in the vagina and bladder. Corticotropin-releasing factor (CRF) receptor and transient receptor potential (TRP) channel protein expression was also significantly, and differentially, affected in vagina, bladder, and colon by both NMS and VBD. Together these data indicate that NMS affects both central and peripheral aspects of the HPA axis, which may drive changes in vaginal sensitivity and the development of comorbid chronic pain and mood disorders.

Chronic pelvic pain in endometriosis: an overview

Chronic pelvic pain (CPP) could be considered nowadays a deep health problem that challenges physicians all over the world. This because its aetiology is still unclear, the course of the disease could vary a lot among different patients and through time in the same patient, and the response to treatments is not every time successful. Among women who underwent laparoscopy for CPP, endometriosis is found in about 1/3 of the cases, while only 25% of women with histological confirmed endometriosis are asymptomatic. A wide range of variables may exert their influence on the resulting pain syndrome in endometriosis; for example, score according to American society for reproductive medicine (rASRM), size of the sub-peritoneal and pelvic wall implants, Douglas obliteration, previous surgery. It is widely accepted nowadays that central nervous system (CNS) and peripheral nervous system (PNS) seems to influence each other and this interconnection play a key role in pain modulation. Moreover, the phenomena induced by endometriosis in the pelvis, including the breakdown of peritoneal homeostasis and the induction of the production of proinflammatory and proangiogenic cytokines, are responsible of altered innervations and modulation of pain pathways in these patients. There are many proposed medical and surgical approach to treat this painful syndrome, although there is necessity of more efforts to create new non-invasive strategies that set a more accurate diagnosis of the causes of endometriotic-related CPP, and therefore facilitate its eradication.

A new technique for inferior hypogastric plexus block: a coccygeal transverse approach -a case report-

Chronic pelvic pain is a common problem with variable etiology. The sympathetic nervous system plays an important role in the transmission of visceral pain regardless of its etiology. Sympathetic nerve block is effective and safe for treatment of pelvic visceral pain. One of them, the inferior hypogastric plexus, is not easily assessable to blockade by local anesthetics and neurolytic agents. Inferior hypogastric plexus block is not commonly used in chronic pelvic pain patients due to pre-sacral location. Therefore, inferior hypogastric plexus is not readily blocked using paravertebral or transdiscal approaches. There is only one report of inferior hypogastric plexus block via transsacral approach. This approach has several disadvantages. In this case a favorable outcome was obtained by using coccygeal transverse approach of inferior hypogastric plexus. Thus, we report a patient who was successfully given inferior hypogastric plexus block via coccygeal transverse approach to treat chronic pelvic pain conditions involving the lower pelvic viscera.

Chronic pelvic pain: multifactorial influences

RATIONALE

Chronic pelvic pain (CPP) is a common and complex disease whose cause is often clinically inexplicable, with diagnosis and treatment being more difficult. From a clinical viewpoint, CPP is defined as non-cyclic, non-menstrual pain lasting at least 6 months and sufficiently severe to interfere with habitual activities and requiring clinical or surgical treatment. Thus, CPP is a syndrome resulting from a complex interaction of the nervous, musculoskeletal and endocrine systems and also influenced by psychological and sociocultural factors. CPP is influenced by emotional aspects with an impact on quality of life, and involving high costs for health services. Its aetiology is not always clear and a cure or significant improvement of symptoms is not always obtained with the treatments employed, with constant frustration of the professionals involved. It can be seen that its treatment is often unsatisfactory, simply providing temporary relief of symptoms.

METHODS

In the present study, we reviewed the bibliography regarding pelvic pain, with emphasis on emotional aspects and on the importance of a multidimensional approach to the care for these patients.

RESULTS AND CONCLUSIONS

New investigations are needed to clarify these relations and interventions in a more effective manner. Interdisciplinary care can minimize the impact of the disease, helping the patients to cope with symptoms and improving their quality of life.

Prevalence and characteristics of chronic pelvic pain among women in Alexandria, Egypt

BACKGROUND

Chronic pelvic pain (CPP) is widespread among women with a significant impact on their health. The nature and severity of pain varies between different women and areas.

OBJECTIVES

To estimate the prevalence CPP and associated dysmenorrhea, and dyspareunia among women attending Family Health Centers in Alexandria, Egypt and to describe the nature and severity of pain as reported by women.

MATERIALS AND METHODS

A cross-sectional study was performed on a sample of 900 ever-married women aged (18-59) years attending three Family Health Centers in Alexandria, Egypt (2007-2008). Personal, social, reproductive, and medical data were collected using a modified Oxfordshire questionnaire. Severity of pain was assessed using both the Verbal Rating Scale and the Visual Analogue Scale.

RESULTS

Prevalence of CPP was 26.6%, dysmenorrhea was 55.3%, and dyspareunia was 40.5%. The three types overlapped. Most women (92%) had CPP of intermittent type and 46.9% had this pain for more than 1 year (1-5 years). Pain was perceived as severe in approximately one third of them (32.2%). Their mean Visual Analog Scale for pain severity was 6.5±2.1. The most frequently mentioned types of pain were moderate cramping pain and moderate heaviness (40%). Factors that increase their pain were mainly full bladder, sexual intercourse, and loaded colon (60, 46.4, and 40%, respectively). Relieving factors were urination and sleep/rest (46.9 and 46.4%, respectively) and use of medications (40%).

CONCLUSION AND RECOMMENDATIONS

The three types of pain were highly prevalent and overlapping among the women studied. CPP was perceived as severe and intermittent by many women. Pelvic pain should receive greater attention both in public education and in clinical practice. Primary care physicians should be prepared to initiate pain management to alleviate women's stress and disability. Women should be educated regarding the importance of seeking medical treatment early.

The relationship between sexual abuse and interstitial cystitis/painful bladder syndrome

Interstitial cystitis/painful bladder syndrome (IC/PBS) is a chronic syndrome characterized by irritative voiding symptoms and pelvic pain or discomfort. IC/PBS represents localized bladder pathophysiologic changes and central nervous system upregulation. Patients exhibit bladder hyperalgesia and allodynia. Childhood sexual abuse occurs in up to 27% of females in the United States. Adults with a prior history of abuse or traumatization demonstrate hypothalamic-pituitary-adrenal (HPA) axis abnormalities, similar to IC/PBS patients. Childhood sexual abuse and physical traumatization are associated with subsequent lifelong risks of chronic pain syndromes. IC/PBS patients have increased rates of sexual abuse or physical traumatization histories compared with controls. IC/PBS patients with abuse histories tend to have greater pain intensity and lesser irritative voiding symptoms compared with nonabused IC/PBS patients. This article reviews the relationship between sexual abuse, HPA axis abnormalities, IC/PBS pathophysiology, and the role of sexual abuse on subsequent IC/PBS.

Is chronic pelvic pain a comfortable diagnosis for primary care practitioners: a qualitative study

Background

Chronic pelvic pain (CPP) has a prevalence similar to asthma and chronic back pain, but little is known about how general practitioners (GPs) and practice nurses manage women with this problem. A clearer understanding of current management is necessary to develop appropriate strategies, in keeping with current health care policy, for the supported self-management of patients with long term conditions. The aim of this study was to explore GPs' and practice nurses' understanding and perspectives on the management of chronic pelvic pain.

Methods

Data were collected using semi-structured interviews with a purposive sample of 21 GPs and 20 practice nurses, in three primary care trusts in the North West of England. Data were analysed using the principles of Framework analysis.

Results

Analysis suggests that women who present with CPP pose a challenge to GPs and practice nurses. CPP is not necessarily recognized as a diagnostic label and making the diagnosis was achieved only by exclusion. This contrasts with the relative acceptability of labels such as irritable bowel syndrome (IBS). GPs expressed elements of therapeutic nihilism about the condition. Despite practice nurses taking on increasing responsibilities for the management of patients with long term conditions, respondents did not feel that CPP was an area that they were comfortable in managing.

Conclusions

The study demonstrates an educational/training need for both GPs and practice nurses. GPs described a number of skills and clinical competencies which could be harnessed to develop a more targeted management strategy. There is potential to develop facilitated self- management for use in this patient group, given that this approach has been successful in patients with similar conditions such as IBS.

High levels of anxiety and depression have a negative effect on quality of life of women with chronic pelvic pain

BACKGROUND

Chronic pelvic pain (CPP) is a common and complex disease whose cause is often clinically inexplicable, with consequent difficulty in diagnosis and treatment. Patients with CPP have high levels of anxiety and depression, with a consequent impairment of their quality of life.

AIMS

The objective of this study was to determine the prevalence of anxiety and depression and their impact on the quality of life of women with CPP.

MATERIALS AND METHODS

A cross-sectional controlled study was conducted on 52 patients with CPP and 54 women without pain. Depression and anxiety were evaluated by the Hospital Anxiety and Depression Scale, and quality of life was evaluated by the World Health Organization Quality of life Whoqol-bref questionnaire. Data were analysed statistically by the Mann-Whitney U-test, the Fisher exact test, chi-square test and Spearman correlation test.

RESULTS

The prevalence of anxiety was 73% and 37% in the CPP and control groups, respectively, and the prevalence of depression was 40% and 30% respectively. Significant differences between groups were observed in the physical, psychological and social domains. Patients with higher anxiety and depression scores present lower quality of life scores.

DISCUSSION

The fact that DPC is a syndromic complex, many patients enter a chronic cycle of search for improvement of medical symptoms. The constant presence of pain may be responsible for affective changes in dynamics, family, social and sexual. Initially the person is facing the loss of a healthy body and active, to a state of dependence and limitations. In this study, patients with higher scores of anxiety and depression scores had lower quality of life and patients with lower scores of anxiety and depression had scores of quality of life. These results show that perhaps the depression and anxiety may be related to the negative impact on quality of life of these patients.

CONCLUSION

In view of this association, we emphasise the importance of a specific approach to the treatment of anxiety and depression together with clinical treatment to improve the quality of life of these patients.

Role of hysteroscopy in evaluating chronic pelvic pain

OBJECTIVE

To provide a survey of various gynecological conditions causing chronic pelvic pain (CPP) that might be diagnosed by hysteroscopy.

DESIGN

Review article.

SETTING

Departments of obstetrics and gynecology and pathophysiology of human reproduction at a university in Italy.

PATIENT(S)

Women affected by CPP.

INTERVENTION(S)

Hysteroscopy.

MAIN OUTCOME MEASURE(S)

Effectiveness in diagnosing intrauterine pathologies that cause CPP.

RESULT(S)

Hysteroscopy is highly effective in diagnosing various gynecological causes of CPP, including adenomyosis, chronic endometritis, Müllerian anomalies, retained fetal bones, endocervical ossification, and intrauterine abnormalities. Furthermore, hysteroscopy may play a primary role in the resolution of some of these conditions.

CONCLUSION(S)

Because it can be executed safely in an office setting without anesthesia, hysteroscopy may be indicated, together with the other noninvasive procedures such as transvaginal ultrasonography, as a first-level investigation in women who are affected by CPP.

Neural mechanisms of pelvic organ cross-sensitization

Clinical observations of viscerovisceral referred pain in patients with gastrointestinal and genitourinary disorders suggest an overlap of neurohumoral mechanisms underlying both bowel and urinary bladder dysfunctions. Close proximity of visceral organs within the abdominal cavity complicates identification of the exact source of chronic pelvic pain, where it originates, and how it relocates with time. Cross-sensitization among pelvic structures may contribute to chronic pelvic pain of unknown etiology and involves convergent neural pathways of noxious stimulus transmission from two or more organs. Convergence of sensory information from discrete pelvic structures occurs at different levels of nervous system hierarchy including dorsal root ganglia, the spinal cord and the brain. The cell bodies of sensory neurons projecting to the colon, urinary bladder and male/female reproductive organs express a wide range of membrane receptors and synthesize many neurotransmitters and regulatory peptides. These substances are released from nerve terminals following enhanced neuronal excitability and may lead to the occurrence of neurogenic inflammation in the pelvis. Multiple factors including inflammation, nerve injury, ischemia, peripheral hyperalgesia, metabolic disorders and other pathological conditions dramatically alter the function of directly affected pelvic structures as well as organs located next to a damaged domain. Defining precise mechanisms of viscerovisceral cross-sensitization would have implications for the development of effective pharmacological therapies for the treatment of functional disorders with chronic pelvic pain such as irritable bowel syndrome and painful bladder syndrome. The complexity of overlapping neural pathways and possible mechanisms underlying pelvic organ crosstalk are analyzed in this review at both systemic and cellular levels.

Relational patterns of couples living with chronic pelvic pain from endometriosis

Chronic pelvic pain (CPP) is a disabling condition affecting 15 to 20% of U.S. women of reproductive age. Endometriosis, one of the most common causes of CPP, is associated with symptoms of pelvic pain, painful sexual intercourse, and infertility. In this qualitative study, the authors examined the relational impact of CPP from endometriosis on 13 couples through narrative interviews conducted individually and jointly. They describe five relational patterns that vary on degree of closeness, how care responsibilities are enacted, the degree to which couples are conjoined in their experiences, and how much their lives are overtaken with the disease. These patterns articulate couples' relational concerns as well as daily management of illness.

A multidisciplinary approach to self care in chronic pelvic pain

Chronic pelvic pain is one of the most difficult conditions encountered by health professionals working with women both in primary and secondary care. The cause is variable, and for some women a diagnosis is never determined. While it is acknowledged that it is a symptom and not a condition, many women and professionals continue to seek a cause and cure. It is contended that this client group is best supported by a multidisciplinary approach to symptom control that incorporates the skills of the gynaecologist, physiotherapist, nurse, psychologist and pain management specialist. This is often difficult to achieve within a resource-limited environment. An alternative approach is suggested using current resources, which provides patient education and support, thus empowering women to influence their health behaviours and situations.

[Pelvic pain by acute symphysis pubis separation after vaginal delivery]

Pelvic pain during pregnancy and postpartum period is common. Pubic separation is a physiologic phenomenon caused by pregnancy and delivery. It's an aetiology of pregnancy and postpartum pain requiring a specialized management in case of severe pain. We report the case of a 34-year-old multiparous woman suffering from severe pubic symphysis pain after twin delivery by vaginal approach, with extraction support, under epidural analgesia. Pubic symphysis separation was diagnosed according both to the clinical symptoms and to the radiology. A local anesthetic infiltration was performed twice to substantially relieve the patient.

Is there any correlation between stages of endometriosis and severity of chronic pelvic pain? Possibilities of treatment

We report herein findings on 181 patients, suffering from pelvic endometriosis confirmed by histology, whose main symptom was chronic pelvic pain (CPP). They attended the outpatient clinic at the 1st Department of Obstetrics and Gynaecology, Semmelweis University in Budapest, between 1 January 1995 and 1 January 2000. The extent of pelvic endometriosis was determined on the basis of the 1985 revised scoring system of the American Fertility Society (R-AFS). The short form of the McGill pain questionnaire was used for the evaluation of CPP. After the first operative intervention, therapy with a gonadotropin-releasing hormone (GnRH) analog was given for 6 months. Second-look laparoscopy was performed 8-10 weeks after the end of GnRH-analog treatment, which was followed by a non-conventionally administered, monophasic oral contraceptive (OC) treatment. In the long term, 118 patients received the non-conventionally administered, monophasic OC treatment, which contained a third-generation progestogen, to be taken continuously for at least 6 months. The other 63 patients who did not receive OC treatment for one reason or another were evaluated as a control group. We analyzed data on CPP before the first surgical intervention, then following therapy with the GnRH analog at the second-look operation, and then after 6, 12, 18 and 24 months. We also reviewed potential causes of CPP, especially focused on endometriosis. No correlation was found between the stage of endometriosis according to R-AFS score and the severity of CPP. At the 24-month follow-up after second-look laparoscopy, the non-conventionally administered monophasic OC treatment was found not only to significantly reduce pain scores, but also the required radical operative solution (hysterectomy plus bilateral adnexectomy) for CPP by OC users.

Chronic pelvic pain in New Zealand: prevalence, pain severity, diagnoses and use of the health services

Chronic pelvic pain (CPP) in women is often debilitating and isolating. Problems with diagnosis continue to make CPP one of the most perplexing conditions in gynaecology, and one of the most difficult to treat.

OBJECTIVES

This paper reports the findings of a population-based study in New Zealand in 2001 designed to investigate the prevalence of chronic pelvic pain in women between the ages of 18 and 50. Chronic pelvic pain was defined as pain that is neither associated with the menstrual cycle nor sexual activity. The prevalence of dysmenorrhoea and dyspareunia was also sought. It further aimed to examine pain severity, diagnoses, and the use of the health services as these facets of CPP affect different groups of women within New Zealand.

METHODS

A random sample of 2261 was generated from the New Zealand Electoral Roll, and a postal questionnaire was administered during 2001. The response rate was 66% (adjusted for non-receivers), giving a study group of 1,160 respondents.

RESULTS

The three-month CPP prevalence rate was 25.4% (95% CI 22.8-27.9). Half of those women reporting CPP (47.7%) remained undiagnosed. The three-month prevalence of dysmenorrhoea was 55.2%, and dyspareunia 19.7%. Recent or past consulters of health services for CPP contained a higher proportion of women with a high pain burden than those not consulting health services. Only one-third of New Zealand women (34%) reported no form of chronic pelvic pain (i.e. no CPP, dysmenorrhoea or dyspareunia). These prevalence rates indicate that CPP should receive greater public education and clinical attention.

Multivariate Genetic Analysis of Chronic Pelvic Pain and Associated Phenotypes

Chronic pelvic pain (CPP) is a common condition in women that is difficult to diagnose. Although heritability estimates have been published for some conditions potentially underlying pelvic pain, the heritability of CPP itself has never been investigated. Using data from 623 MZ and 377 DZ female twin pairs aged 29-50 from an Australian twin cohort, we found an increased CPP concordance among MZs compared to DZs, with tetrachoric correlations of 0.43 (95% CI: 0.26-0.58) and 0.11 (95% CI: -0.16-0.38), respectively. This corresponded to a heritability of 0.41 (95% CI: 0.25-0.56). Lack of correlations with environmental indicators suggested that violation of the equal environments assumption was not responsible for this effect. Multivariate Cholesky decomposition models incorporating CPP and significantly correlated phenotypes showed that the entire CPP heritability could be explained by genetic variance underlying endometriosis (38%), dysmenorrhoea (23%), fibroids (24%), and somatic distress (15%), the latter a possible indicator of increased nociception. CPP itself is unlikely to be a useful independent phenotype to conduct genetic aetiological studies; contributing conditions such as endometriosis and variation in nociception are likely to provide more useful phenotypes.

Chronic pelvic pain and irritable bowel syndrome

This article describes the common association between chronic pelvic pain and irritable bowel syndrome. The aim of the diagnosis and management of chronic pelvic pain and irritable bowel syndrome is to improve the quality of life of the patient. Methods of diagnosis, treatment and overall management for these two challenging conditions are outlined in this article.

Diagnosis and management of chronic pelvic pain

Chronic pelvic pain is difficult to diagnose and to treat [81] because of the multiple and often overlapping causes [82]. A systematic approach aids in the thorough evaluation and appropriate therapy. At the initial visit(s), a thorough history should be taken and complete physical examination performed. Screening for co-existing conditions, such as depression, narcotic dependency, and physical, sexual, or emotional abuse is crucial so these issues may be addressed immediately while additional causes for pelvic pain are evaluated. The relative likelihood of gastrointestinal, urologic, musculoskeletal, or gynecologic etiology must be considered to guide a more thorough initial evaluation. With gynecologic chronic pelvic pain, differentiation between hormonally responsive and nonresponsive conditions is helpful for diagnosis and treatment. Therapy can then be instituted or an appropriate referral made.

Chronic pelvic pain in the community--symptoms, investigations, and diagnoses

OBJECTIVES

This study was undertaken to investigate the overlap between chronic pelvic pain, dysmenorrhea, dyspareunia, irritable bowel syndrome, and genitourinary symptoms in the community and also to examine associated investigations and diagnoses.

STUDY DESIGN

A postal questionnaire was used to survey 3916 women aged 18 through 49 randomly selected from the Oxfordshire Health Authority Register. The number of responders was 2304 (74% of 3106 questionnaire recipients). Chronic pelvic pain was described as recurrent or constant pelvic pain of > or =6 months' duration unrelated to periods, intercourse, or pregnancy. Case patients (n = 483) were subgrouped as follows: (1) chronic pelvic pain only, (2) chronic pelvic pain and irritable bowel syndrome, (3) chronic pelvic pain and genitourinary symptoms, and (4) chronic pelvic pain, genitourinary symptoms, and irritable bowel syndrome.

RESULTS

Half the women with chronic pelvic pain also had either genitourinary symptoms or irritable bowel syndrome, or both. Prevalences of dysmenorrhea and dyspareunia were higher among women with chronic pelvic pain (81% and 41%, respectively) than among women without chronic pelvic pain (58% and 14%, respectively); rates did not differ among the chronic pelvic pain subgroups. Irritable bowel syndrome and stress were the most common diagnoses received by patients with chronic pelvic pain, but 50% had never received a diagnosis.

CONCLUSIONS

There is substantial overlap between chronic pelvic pain and other abdominal symptoms in the community. Despite a high prevalence of chronic pelvic pain, many women have never had the condition diagnosed.
